Restoring Lost Heritage, Lewis Culliver

Masters in Architecture Program: Theses

One of the best streets to explore in Omaha is N. 24th Street. Many buildings showcase larger than life, vibrant murals that express the creative nature and spirit of this part of historic North Omaha. The murals represent a healing element for the community; many murals cover structures that are in various states of disrepair. Community gardens have risen to fill voids left by traumatic development practices, such as the implementation of the north freeway.

Despite having lost a large part of its heritage, including hundreds of homes and businesses that were destroyed to make way for the north freeway, …

Post-Earthquake Assessment And Numerical Modeling Of Freestanding Heritage Structures, M. Khalid Saifullah, Christine E. Wittich

Department of Civil and Environmental Engineering: Faculty Publications

Historic and heritage structures are particularly vulnerable to earthquakes, where damage or collapse can not only lead to loss of a structure but also the loss of irreplaceable heritage. Many heritage structures can be classified as freestanding (detached) structures, including unreinforced masonry walls, classical multi-drum columns, and statue-pedestal systems. However, the seismic response of freestanding structures (sliding, rocking, rock-slide, overturning) is poorly predicted by existing methods due to geometric non-linearities as well as sensitivity to interface conditions and modeling parameters. Previous studies have focused on analytical modeling of simplified systems and/or experimentation under controlled laboratory conditions. In contrast, this paper …
